HARRY BITNER, OF BERWYN, ILLINOIS, ASSIGNOR TO ARCADE MANUFAC- TURINGCOMPANY, OF FREEPORT, ILLINOIS, A CORPORATION OF ILLINOIS.

CORK-FULLER.

Specification of Letters Patent.

Patented Feb. 26, 1907.

To tZZ whom, t may concern:

Be it known that I, HARRY BITNER, a citizen of the United States ofAmerica, residing at Berwyn, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements inCork-Fullers, of which the following is a specification.

My invention relates to certain new and useful improvements incork-pullers and its object is to produce a device of this class whichshall have certain advantages, which will appear more fully and at largein the course of this specication.

To this end my invention consists in certain novel features, which areshown in the accompanying drawings as embodied in my preferred form ofconstruction.

In the aforesaid drawings, Figure l is an elevation of a cork-extractorembodying my invention, one of the casing-sections being removed andcertain portions being shown in central longitudinal section toillustrate the construction. lfig. 2 is a transverse section in the line2 2 of I1 ig. 1. Fig. 3 is a perspective view of the. corkscrew-carrier.Big. 4 is a perspective view of the bearing-clip. Fig. 5 is a centrallongitudinal section through the bearing-clip, showing the manner inwhich it is secured to the worm.

Referring to the drawings, A is a suitable case in which is non-rotatebly and reciprocably guided a corkscrew-carrier B, adapted to bereciprocated by a crank C, moved by an operating-lever or handle I) andconnected with the corkscrew-carrier by a link or pitman c.

E is a suitable nut threaded to embrace a worm F, swiveled in thecorkscrew-carrier, the said nut being reciprocable in the guideway ofthe case below the corkscrew-carrier. A block G is pivoted to the nut Eand is shiftable by means of a lever II, actuated by a cam I on theoperating-shaft, the said block being adapted when moved to lock the nutalternately to the corkscrew-carrier and case during the pulling andstripping movements of the device.

All the parts heretofore set forth are old and well known and are fullyillustrated in approximately the same relations as herein shown in manyprior patents, among them the patent to Charles Morgan, No. 620,949.

My present invention relates particularly to the means for rotatablysecuring the worm F in the corkscrew-carrier B, and it will be obviousthat this feature will operate as successfully and perform its functionsin the same way in any device of this class where the nut serves thepurpose of rotating the worm and where the carrier is movedlongitudinally relatively with respect to the nut to effect theoperation. This will include, obviously, eXtractors of the long-stroketypesuch, for example, as that illustrated in the patent to Ennis, No.642,691-extractors of the double-stroke type-such, for example, as areillustrated in the patent to Tscherning, No. 728,517-and many othersdevices.

The particular swiveling mechanism forming the basis of my presentinvention will now be described. The corkscrew-carrier B is providedwith a chamber b, preferably eX- tending from front to back thereof, andthe lower wall of said chamber is slotted or notched from one side,preferably from the front at b. J indicates a spring bearingclip,preferably of .hardened spring-steel. This c ip, it will be seen, isU-shaped in form, one of the legs thereof having a perforation y',through which the worm I" can be passed, and the other leg having anupwardlystamped conical bearing-socket j, adapted to receive a conicalpoint f, provided on an enlarged head j" on the upper end of the worm.The worm is placed in position in the bearing-clip as illustrated inFig. 5-f. e., it is screwed through the perforation until its head bearsagainst the perforated leg of the bearing-clip-when the pointed end ofthe head is snapped into place in the conical socket. Thereupon thebearing-clip and the head of the worm can be inserted in thecorkscrew-carrier, the worm passing through the slot b and theupwardly-projecting bearingsocket j passing through a groove b2,provided for the 'purpose in the upper side of the chamber t ofthecorkscrew-carrier B. Inward movement of the clip and worm is limitedby engagement of the clip with a shoulder b3 in the upper face of thechamber l), and when the carrier is placed in the guideway of the caseoutward movement is prevented by engagement of the clip with thevertical xvalls of the guideway, as illustrated in It will be observedthat by the means set forth herein the worm is furnished with ahardened-steel bearing and is also arranged IOO so that practically noside thrust against the practically soft material of thecorkscrewcarrier can take place. In practice the worms will be furnishedto the trade with the clip in place upon them, so that when a wormbreaks and a new one is inserted a fresh unworn bearing will be used. Itwill also be obvious that the worm can be very readily removed andreplaced without the use of any special tools or the assembling of anyparts which are not furnished in their assembled parts by themanufacturer.

I claim as new and desire to secure by Letters Patentl. In a device ofthe class described, the combination with a longitudinal guide, acorkscrew-carrier, a worm, and a nut threaded to embrace the worm, of aremovable bearing for the upper extremity of the worm, adapted to occupya suitable chamber in the corkscrew-carrier and to be removed from saidchamber while secured to the worm.

2. In a device of the class described, the combination with a suitableguide, a relatively movable nut and corkscrew-carrier and a wormthreaded in the nut, of a bearing for the upper extremity of the worm,secured to said worm and adapted to be placed in and removed from achamber provided in the corkscrew-carrier, while secured to the worm.

3. In a device of the class described, the combination with a suitableguide, a relatively movable nut and corkscrew-carrier and a wormthreaded in the nut, of a bearing-clip secured to the head of the wormand adapted to be inserted in and removed from a suitable chamber in thecorkscrew-carrier.

4. In a device of the class described, the combination with a suitableguide, a relatively movable nut and corkscrew-carrier and a wormthreaded in the nut, of a U- shaped bearing-clip having a perforation inone leg through which the worm can be threaded to bring the head thereofwithin the clip, said clip being adapted to be inserted in place in asuitable chamber in the corkscrewcarrier.

5. In a device of the class described, the combination with a suitableguide, a relatively movable nut and corkscrew-carrier and a wormthreaded in the nut, of a U- shaped bearing-clip having a perforation inone leg through which the worm can be threaded to bring the head thereofwithin the clip, said clip being adapted to be inserted in place in asuitable chamber in the corkscrew-carrier, the worm passing through anotch in the bottom of the chamber.

6. In a device of the class described, the combination with a suitableguide, a relatively movable nut and corkscrew-carrier and a wormthreaded in the nut, of a U- shaped bearing-clip arranged to embrace thehead of the worm, the upper leg thereof having a socket for the head,said clip being adapted to be inserted in a suitable chamber in thecorkscrew-carrier.

7. In a device of the class described, the combination with a suitableguide, a relatively movable nut and corkscrew-carrier and a wormthreaded in the nut, of a U- shaped bearing-clip arranged to embrace thehead of the worm, the upper leg thereof having a socket for the head,said clip being adapted to be inserted in a suitable chamber in thecorkscrew-carrier, the socket in said clip passing along a groove in theupper face of said chamber.

8. In a device of the class described, the combination with a suitableguide, a relatively movable nut and corkscrew-carrier and a wormthreaded in the nut, of a U- shaped spring-clip having a socket in itsupper leg and a perforation in line with the socket in the lower leg,the worm being adapted to be threaded through the perforation andsnapped into place in the socket, the clip being adapted thereupon to beplaced in a suitable chamber in the corkscrew-carrier, the worm passingthrough a notch in the bottom of the carrier and the socket runningalong a groove.

9.

l0. In a device of the class described, the combination with asubstantially inclosed guideway, a nut and corkscrew-carrier movable inthe guideway and a worm threaded in the nut, of a U-shaped bearing-clipembracing the head of the worm and lying within a chamber in thecorkscrew-carrier, said clip being held in place by engagement with thewalls of the guide.
